sleeping out in winter

In minus 35(wind chill-64) two days before I got frost bitten). We had 3 to a 2 man tent. Just my fingers and toes. I said them if we have another war like in Korea I'm going to desert.

Depends how a individual can handle or adapt to the cold and what equipment they have

Depends a lot on your sleeping bags and clothing.

If you don't have the right gear, don't try it, you can die without knowing it. Get an expert to help outfit you.

Sissy hubby did it overnight in 15 below zero plus the wind chill. My bull told him he had to..

Until I get sick, so about 48 hours.

Zero.. bugger that 😳
